Abstract
A converter includes a first switch coupled between a first input terminal and a first terminal of an inductor, and a second switch coupled between a second terminal of the inductor and a second input terminal. A third switch is coupled between the second terminal of the inductor and a first output terminal, and a fourth switch is coupled between the first terminal of the inductor and a second output terminal. A capacitor is coupled between the first and second output terminals. A control circuit monitors a regulated voltage between the first and second output terminals. During a charge phase, the first and second switches are closed to charge the inductor. During a discharge phase, the third and fourth switches are closed to charge the capacitor and increase the regulated voltage.
